Abstract: An information storage circuit having a first memory portion configured to store a first validity bit and first data; a second memory portion configured to store a second validity bit and second data; and a subcircuit configured to: write the first data to the first memory portion and the second data to the second memory portion sequentially; and set the first and second validity bits to indicate which of the first data and second data is valid.

Abstract: An apparatus and corresponding method for outputting a protocol pulse based on a speed signal representing speed of an object. The apparatus includes a zero-crossing circuit, and a delay circuit. The zero-crossing circuit is configured to output the protocol pulse at a zero-crossing of the speed signal. The delay circuit is coupled to the output of the zero-crossing circuit and configured to delay the protocol pulse. A first edge of the protocol pulse is asynchronous with a clock, and a second edge of the protocol pulse is synchronous with the clock.

Abstract: A method for conducting group travel, wherein a subsequent group travel participant follows a group travel participant travelling ahead or the subsequent group travel participant drives to a current destination of group travel participant travelling ahead, includes the steps of: assigning a group travel identifier for a journey of the group travel participant travelling ahead; passing on the group travel identifier from the group travel participant travelling ahead to the subsequent group travel participant; transmitting navigation information of the group travel participant travelling ahead to a distribution unit in a context with the group travel identifier; transmitting the navigation information from the distribution unit to the subsequent group travel participant; and using the navigation information transmitted from the distribution unit by the subsequent group travel participant.

Abstract: Embodiments relate to multi-contact sensor devices and operating methods thereof that can reduce or eliminate offset error. In embodiments, sensor devices can comprise three or more contacts, and multiple such sensor devices can be combined. The sensor devices can comprise Hall sensor devices, such as vertical Hall devices, or other sensor types in embodiments. Operating modes can be implemented for the multi-contact sensor devices which offer significant modifications of and improvements over conventional spinning current principles, including reduced residual offset.

Abstract: The invention relates to a volume-controlled four-stroke reciprocating internal combustion engine comprising a first cylinder, in which a first piston that is operationally connected to a crankshaft via a first connecting rod, is arranged so as to be displaceable in a reciprocating motion, and at least one second cylinder, in which a second piston that is operationally connected to the crankshaft via a second connecting rod is arranged so as to be displaceable in a reciprocating motion. The engine further includes a fresh air tract for the second cylinder, in which an expansion/compression machine is arranged in the direction of flow of fresh air before a gas exchange inlet valve of the second cylinder, wherein the expansion/compression machine is the first cylinder. The volume-controlled internal combustion engine as per the invention has great potential for saving fuel and thereby for reducing CO2.

Abstract: A method is provided for operating a volume-controlled internal-combustion engine having an intake tract and an exhaust system. An expansion machine is arranged in the intake tract in the flow direction of a combustion air in front of an inlet valve of the engine. An output shaft of the expansion machine is coupleable with an output shaft of the engine. A heat exchanger is arranged in the exhaust system. Before combustion air flows through the expansion machine, it is heated in the heat exchanger by exhaust gas of the internal-combustion engine. The method achieves an efficiency improvement in an internal-combustion engine with a volume-controlled load control at partial load.

Abstract: A drive unit for a hoist, an elevator in particular, with a motor (6), a transmission (2), a breaking means (4) and a housing (8) is characterized in that said motor (6) and said breaking means are together arranged in said housing (8). Furthermore, at least one part of said transmission (2) can be arranged in said housing (8) as mounted or built-in transmission so that said housing (8) for the largest part also forms the transmission housing.

Abstract: For controlling and surveying the operation of elevator systems pulse generators are used which are integrated into antifriction bearings of mutually pivotable structural members of the elevator system. By measuring pulse numbers and pulse frequency, conditions of movement and positions of moving parts, like e.g. the elevator cage (5) and the doors (13), can be detected and evaluated in a computer.
